Each part is laser trimmed to the desired threshold voltage which can be specified from 2.1V to 6.0V, in 0.1V steps. The device includes a comparator, low-current high- precision reference, laser-trimmed divider, hysteresis circuit and output driver. The TC54 is available with either an open- drain or complementary output stage. In operation, the TC54's output (VOUT) remains in the logic HIGH state as long as VIN is greater than the specified threshold voltage (V – DET). When VIN falls below V – DET, the output is driven to a logic LOW. VOUT remains LOW until VIN rises above V – DET by an amount VHYST, whereupon it resets to a logic HIGH. FUNCTIONAL BLOCK DIAGRAM VOLTAGE DETECTOR Output form: N = Nch Open Drain C = CMOS Output Detected Voltage: Ex: 21 = 2.1V; 60 = 6.0V Extra Feature Code: Fixed: 0 Tolerance: 1 = ± 1.0% (custom) 2 = ± 2.0% (standard) Temperature: E: – 40 °C to + 85°C Package Type and Pin Count: CB: SOT-23A-3*, MB: SOT-89-3, ZB: TO-92-3 Taping Direction: Standard Taping Reverse Taping No suffix: TO-92 Bulk *SOT-23A-3 is equivalent to EIAJ (SC-59).
